  1. Heredity, Genetics, and Cells review

  2. Which organelle produces most of the energy needed by a cell?A. mitochondriaB. chloroplastsC. ribosomesD. Golgi bodies 1

  3. A. mitochondria And the answer is…

  4. In what type of cells would you expect to find a lot of mitochondria?A. skin cellsB. blood cellsC. bone cellsD. muscle cells 2

  5. And the answer is… D. muscle cells

  6. Which of the following is NOT a similarity between plant and animal cells.A. both contain ribosomes to produce proteinsB. both contain chloroplasts to capture energy from the sun and convert it to foodC. both contain chromatin that contain genetic information for the cellD. both contain a nucleolus where ribosomes are made 3

  7. B. both contain chloroplasts to capture energy from the sun and convert it to food And the answer is…

  8. Name two structures that are not found in the cell shown here but are found in plant cells.A. cell wall, chloroplastsB. cell wall, chromatinC. nucleolus, chloroplastsD. lysomes, nucleolus 4

  9. A. cell wall, chloroplasts And the answer is…

  10. What term means the smallest unit that is able to perform the basic functions of life? 5

  11. cells And the answer is…

  12. Which structure listed is responsible for direction of all of the cell’s activities?A. AB. BC. CD. D 6

  13. D. D And the answer is…

  14. What term means a structure that is made up of different tissues working together to perform a particular function? 7

  15. organ And the answer is…

  16. What term means an individual living thing made up of one or many cells that is capable of growing and reproducing? 8

  17. organism And the answer is…

  18. What is the function of a cell membraneA. to protect and support the cellB. to perform different functions in each cellC. to control what enters and leaves the cellD. to form a hard covering for the cell 9

  19. C. to control what enters and leaves the cell And the answer is…

  20. Which organelle is the control center of a cell?A. mitochondriaB. ribosomeC. chloroplastD. nucleus 10

  21. D. nucleus And the answer is…

  22. What term means a group of similar cells that are organized to do a specific job? 11

  23. tissue And the answer is…

  24. Two forms of the same gene are known as Alleles Chromosomes Genotypes Sex cells 12

  25. And the answer is… Alleles

  26. Long, thin fibers that carry information that controls the cell’s activities are Nucleic acids Dominant traits Recessive traits chromosomes 13

  27. And the answer is… D. chromosomes

  28. If you cross a white flower (with genotype pp) with a purple flower (with the genotype PP), the possible genotypes and phenotypes possible are PP Pp Purple flowers White flowers A and B only B and C only A , B and C only A, B, C and D only 14

  29. And the answer is… F. B and C only

  30. The passing of traits from parents to offspring is Probability Heredity Recessive Meiosis 15

  31. And the answer is… B. Heredity

  32. B is for brown eyes and b is for blue eyes. Cross a heterozygous with a homozygous recessive. What is the percentage of the offspring that are heterozygous? 25% 50 % 75% 0% 16

  33. And the answer is… B. 50 %

  34. H is for hairy fingers and h is for non-hairy fingers. Cross a heterozygous with a heterozygous. What are the phenotypes and genotypes? HH, hairy fingers Hh non-hairy fingers hh, non-hairy fingers Hh, hairy fingers A and B only B and D only A, B and C only A, B and D only A, C, and D only 17

  35. And the answer is… I. A, C, and D only

  36. If you cross two rabbits that have the genotype Bb, what are the possible genotypes for the offspring? BB bb Bb bB A and B only A, B and C only A, B and D only A, C and D only B, C and D only A, B, C and D only 18

  37. And the answer is… F. A, B and C only

  38. What is the part of a chromosome that carries information for a specific trait called? Nucleic acid Gene Genotype Phenotype 19

  39. And the answer is… B. Gene

  40. A zygote is A male reproductive cell A female reproductive cell A newly formed cell after the union of a sperm and egg Both male and female reproductive cells 20

  41. And the answer is… C. A newly formed cell after the union of a sperm and egg

  42. Identify the statement that best states the difference between dominant and recessive traits. Recessive traits show up more often than dominant traits. Recessive traits show up as often as dominant traits. Recessive traits show up less often than dominant traits. Recessive and dominant traits are the same. 21

  43. And the answer is… C. Recessive traits show up less often than dominant traits.

  44. T is for thin lips and t is for full lips. Cross a homozygous dominant with a heterozygous. Identify the percentage of offspring with thin lips and the correct genotypes for thin lips. Choose all that apply. TT Tt 50% 100% 22

  45. And the answer is… A , B, and D

  46. A population of mice is evenly divided into two groups, and each group is placed on an isolated island with no existing mouse population. Which statement best explains the difference in the mouse populations on Island A and Island B at the end of 20 years? • On Island A, the allele for gray fur was dominant, while on Island B, the allele for brown fur was dominant. • More brown mice were in the half of the original population that was sent to Island B than in the group sent to Island A. • Conditions on Island B favored the brown-furred individuals, while both fur colors were evenly advantaged on Island A. • The recapturing of mice on Island A and Island B was done differently. 23

  47. And the answer is… • C. Conditions on Island B favored the brown-furred individuals, while both fur colors were evenly advantaged on Island A.

  48. The base sequence of nucleotides in a DNA strand that compliments the DNA base sequence ACGAT is • TGCTA • ACGAT • CGCTA • TGCAT 24

  49. And the answer is… • TGCTA

  50. In a plant that has red flowers, red flower color, R, is completely dominant to white flower color, r. If the plant is heterozygous for flower color, which alleles will be carried by the gametes it produces?   • R and r • R only • r only • Rr only 25
